What I did think was that I would like to try again sometime when there would be clouds in the sky. Then I thought, "Wait a minute, ya big dummy. You can put clouds into that photo." So I did. While I was at it, I also toned down the lighting. It's just an alternative version, that's all.
Here are both edits; the newer edit is the first. You saw the second one yesterday if you dropped by, Seeing them together, I think I prefer to whiter or bluer lights of the original version (second photo).
I had taken a few more photos, so sometime after after re-editing the above photo, I wondered what I could do with my pic of the vacuums. Neither the original version nor the monochrome conversion inspired me. Then I decided to leave some colour (aka selective colour) in the b&w version. It's certainly more interesting and appealing than it it had been, at least to me, despite the fact that some photogs consider selective colour to be cheesy.
Later, I decided to apply the same idea idea (selective colour) to another photo of the car wash itself, just leaving the top signage as it was.
I didn't do all of these edits in one sitting. I came back to computer at different times and just fiddled around. As I mentioned earlier and again in retrospect, I think I would prefer brighter, bluer lighting, but this is where my muse took me at the time.
Live and learn. Experiment and ruminate.
Addendum: I re-edited. too blue? Not bright enough? I just don't know.
